Subject: GSI grain bin power sweep engagment problems


NE North Carolina
I have two bins that I am trying to unload with the sweep augers and they will not engage. These are newer bins about 3-4 years old and when I try to pull the rod that engages the sweeps they will not pull all the way out. One only goes a couple inches and the other goes to just about where it engages. Any one else had this problem or know how to fix it.

don't have GSI, but most of them need to line-up as they engage. Try turning the pulley by hand........or as the auger is slowing down after shut off try to engage.

I had that problem the 2 or 3rd year I had my GSI bin & powersweep. The cog in the gearbox was bad and wouldn't let the sweep engage. Bin repairman says they should be changed every 2-3 yrs, depending on how many times you unload the bin. I've also had some problems with bolts vibrating loose inside the gearbox. You also may have a bunch of corn inside the gearbox which is preventing the cog to move forward far enough to engage. Shovel corn away from the sump the best you can and unbolt the rear access plate. I built a box to go around mine to keep corn from sliding down into it. If you haven't been, you need to be greasing the zerks in the gearbox & oil the chain every year. I also used powdered graphite on all the control arms inside the gearbox. GP doesn't collect dust like oil does. Easiest is to do it as soon as you empty the bin so you don't forget when you go to fill it the next fall.

BTW, When I pull the engagement lever out I put a pair of lock pliars on it to keep it from disengaging on it's own. I think originally it wasn't adjusted right & the cogs didn't engage completely as it would pop out once in awhile while running the sweep.

We have GSI bins and have similar issues every once in a while. Doing what FarmerFrank has suggested solves the problem for us. I have busted/lost the shear bolt just below the 90 degree gear box on the sweep inside at the center of the bin before which was a welcome fix considering what I thought could have been wrong. Good Luck!

Sometimes you just need to turn the unload auger on, then off and then try to pull the handle out all the way. You can feel in the handle when it will line up.

My guess is the engaging cogs (pawls??) or whatever they're called are worn down. They're bronze, I believe on the ones I've seen & replaced. Seems like you should be able to get more than a couple of years (=3-4?), but maybe they weren't adjusted correctly initially. They're easy to replace....once you can get the corn off the center cover!

Boogs idea is good re. a vise-grip. Sometimes if the power sweep is under a heavy load, it will cause the engqagment clutch to pull backwards & disengage or at least wear out the edges.

Good luck.

I agree with Ron. That is what happens with ours, the bronze cog breaks and you have to clean off the center sump and take a cover off to get at it.

Is it a green (sukup) sweep in your gsi bin? If so, it is the cog, poor design.
If it is red, it is not a sukup in the gsi bin. These appear to me to be much better.
